Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull ext2, ext3 and quota fixes from Jan Kara:
"Interesting bits are:
- removal of a special i_mutex locking subclass (I_MUTEX_QUOTA) since
quota code does not need i_mutex anymore in any unusual way.
- backport (from ext4) of a fix of a checkpointing bug (missing cache
flush) that could lead to fs corruption on power failure
The rest are just random small fixes & cleanups."
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
ext2: trivial fix to comment for ext2_free_blocks
ext2: remove the redundant comment for ext2_export_ops
ext3: return 32/64-bit dir name hash according to usage type
quota: Get rid of nested I_MUTEX_QUOTA locking subclass
quota: Use precomputed value of sb_dqopt in dquot_quota_sync
ext2: Remove i_mutex use from ext2_quota_write()
reiserfs: Remove i_mutex use from reiserfs_quota_write()
ext4: Remove i_mutex use from ext4_quota_write()
ext3: Remove i_mutex use from ext3_quota_write()
quota: Fix double lock in add_dquot_ref() with CONFIG_QUOTA_DEBUG
jbd: Write journal superblock with WRITE_FUA after checkpointing
jbd: protect all log tail updates with j_checkpoint_mutex
jbd: Split updating of journal superblock and marking journal empty
ext2: do not register write_super within VFS
ext2: Remove s_dirt handling
ext2: write superblock only once on unmount
ext3: update documentation with barrier=1 default
ext3: remove max_debt in find_group_orlov()
jbd: Refine commit writeout logic
